Answer 1

1) First of all, try cleaning and restarting your Project. In most of the cases this will resolve the issues.

2) If problem still persists:

Import multidex dependency:

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

In your manifest add the MultiDexApplication class:

    <application
        ...
        android:name="android.support.multidex.MultiDexApplication">
        ...
    </application>

If your app already extends the Application class, you can override the attachBaseContext() method and call MultiDex.install(this) to enable multidex .

protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}

Finally, update your build.gradle by adding multiDexEnabled true :

defaultConfig {  
        ...
        multiDexEnabled true  
    }
